Application filed (lctober 15, 1904. Serial No. 228,658.

Patented Sept. 4, 1906.

To all whom it may concern.-

Be it known that we, CARY A. NEYLAND and HENRY G. N AGEL, citizens ofthe United States, and residents of Lewiston, in the county of NezPerces and State of Idaho, have invented a new and Improved Current-Motor, of which the following is a full, clear, and exact description.

Our invention relates to that class of devices known as current-motors,and has for its object the utilization of the maximum amount of forcethat the current in any stream is capable of imparting.

With these and other objects in view our invention consists in thecombination and arrangement of parts, as will be more fully describedhereinafter and definitely set forth I over the water. This isaccomplished by sliding the reciprocating bar 15 on the pin 21 from oneend of the slot 20 to the other. In order to perform this operationautomatically, the end of one of the paddles, such as 2, is connected bymeans of a rod 23 to a sliding member 24, which operates in a slot 25 inthe bar 15. The length of the slot 25 is such that when the paddlearrives near the end of-its stroke the sliding member 24 will strike theend of the slot and push the bar 15 toward the opposite paddle, so thatthe pin 21 is at the opposite end of the slot 25. Since the paddle 2 isbeing elevated at this time by the cam 38 the yoke 12 swings backwardand through its connection with the bar 15 rocks the latter upon the pin20, whereby toswing in the claims. the yoke 13 forward to lower thepaddle 3.

Reference is to be had to the accompany- The connection of the bars 1617 with yokes ing drawings,forming a part of this specifica- 12 13 beingat a higher level than their contion, in which similar characters ofreference nection with the bar 15 tends to lower the indicatecorresponding parts in all the views.

Figure 1 is a plan view of the current-motor, showing it connected totwo pumps. Fig. 2 is a side elevation. Fig. 3 is an end view, and Figs.4 and 5 are detail views showing the cam-surface for raising thepaddles.

Our motor consists of a base 1, upon which are supported paddles 2 3.These paddles are pivotally mounted upon brackets 4 5, and thesebrackets are themselves mounted on vertical pivots, so that they willswing in a horizontal direction. By means of this mounting the paddles 23 have a universal motion about the point at which they are connected tothe brackets 4 5. The paddles 2 and 3 are further supported by means ofrods 6 7, which are pivotally attached to the paddles at 8 and 9 by anysuitable means and also at points 10 and 11 on yokes 12 and .13. Theseyokes are pivotally mounted on the base, so that they can swing on ahorizontal axis passing through the pivots which bear in eyes 14. Theother sides of the yokes 12 and 13 are connected with a reciprocatingbar 15 by means of rods 16 17 and eyes 18 and 19. This reciprocatingmember 15 has a slot 20, extending in a horizontal direction equaldistances on each side of its center, and extending through this slot isa pin 21, mounted upon the base 1. This pin 21 has a head 22 to preventthe bar from sliding off the pin. The object of this construction is toraise and lower the ends of the paddles which project corresponding endof the bar when the yoke is swung backward.

The provision of the pin-and-slot mounting for the bar permits of agreater swing of the yoke, and as a consequence a greater verticalmovement of the paddle, since the corresponding arm of the leverislengthened and shortened in synchronism with the swing of the yoke.After the paddle has been returned near the beginning of its stroke thesliding member 24 again strikes the other end of the slot 25 and returnsthe reciprocating bar to its original position. This operation causesthe paddles to rise and fall by reason of the fact that they areconnected with the ends of the bar 15 and the rods 7 17 and 6 16,respectively.

At a certain distance from the bracket 4 and on the paddle 2 isconnected the end of a chain 26, which is passed around an idler 27 andconnected to a block 28. At a corresponding distance from the bracket 5and on the opposite side thereof a similar chain 29 is connected to theother addle 3 and is passed around an idler 30. T e idlers 27 and 30 areso placed that they will properly direct the block 28 for transmittingits motion to the devices intended to be operated upon. In this casethere are two grammatically, which are intended to be operated by themotor. In order to connect the block 28 with these pumps, levers 31 and32 are pivotally mounted at 33 34 on the base pumps shown dia- 1. Ineach end of these levers are formed slots adapted to engage pins on theblock 28 and on piston-rods 36, respectively.

In order to insure the simultaneous operation of the two paddles andprevent vibration due to lost motion, they are connected by means of arod 37, pivotally attached at equal distances on opposite sides of thebrackets 4 5.

In order to aid the reciprocating bar in raising the paddles at the endof their effective stroke, earns 38 are fastened to the base 1 and madeof such sha e that they will gradually raise the arms 0 the paddles 2and 3 as they approach the end of said stroke.

Our invention it especially adapted to be used for pumping water forirrigation, but may also be used for other purposes.

While the above is one form of our invention, we do not wish to belimited to the pre cise details therein set forth, but only in so far asstated in the claims.

In operation, the motor being placed in the stream, the connection ofthe blades is such that one of them will be in its lowermost positionand will be engaged by the current, as

shown in Fig. 2. The force of the current tends to move the blade in thedirection of travel thereof, this motion bein permitted by the mountingof the blade. s the blade 3 moves toward its companion blade, itsenagement with the cam 38 will tend to lift it om the water, while atthe same time through its connection with the blade 2 the latter will beturned upon its pivot to move the vane part thereof upstream and intocontact with the water. The connecting-bar 15 is rocked u on its pivotthrough its connection with t e bracket 13 when the outer end of theblade is lifted to depress the adjacent end of the bar 15 and lift theopposite end thereof and through its connection with the bracket 12tends to lower the vane part of the blade 2 into the water.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent 1. In a current-motor, the combination of abase, a plurality of paddles mounted on said base so as to have avertical and horizontal motion, connections between said paddles so thatthey Wlll operate in unison, and a flexible connection between saidpaddles for transmitting the power produced, substantially as described.

Y 2. In a current-motor, the combination of a base, a plurality ofpaddles mounted on said base so as to have a vertical and horizontalmotion, means for elevating and lowering said paddles automatically atthe respective ends of their stroke, means for connecting said paddlesso as to operate in unison, and a fflexible connection between saidpaddles for l transmitting the power produced thereby,

substantially as described.

3. In a current-motor, the combination of a base, a plurality of paddlesmounted on said base so as to have a vertical and horizontal motion,means for elevating and lowering said paddles automatically at therespective ends of their stroke, means for connecting said paddles so asto operate in unison, and a chain connecting the paddles fortransmitting the power produced thereby, substantial y as described.

4. In a current-motor, the combination of a base, a plurality of paddlesmounted on said base so as to have a vertical and horizontal motion,means for elevating and lowering said paddles automatically at therespective ends of their stroke, means for connecting said paddles so asto operate in unison, and a chain, working over pulleys and connectingthe paddles, for transmitting the-power produced thereby, substantiallyas described.

5. In a current-motor, the combination of yoke for supporting eachpaddle, connections between each yoke and its paddle and also betweeneach yoke and a reciprocating bar, which is adapted to raise and lowerthe paddles, a connection between one of the paddles and thereciprocating bar, for operating the same, and means connecting thepaddles for operating them in unison and also for transmitting power.

In testimony whereof we have signed our names to this specificationinthe presence of two subscribing witnesses.
